Simply multiplying by the product of the denominators will eliminate fractions, but may require reduction of fractions in the answer. If the "fractions" are rational expressions, extraneous solutions may be introduced.
I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:

So, we know that 5/2 gallons cost 60 dollars, which means

To find the cost of a single gallon, we have to solve the equation for g:

Answer:
All of the above
Step-by-step explanation:
The question is asking you which equation you can use for you to find the value of the undefined variable, n.
In this case, all of the equations above are eligible to find the value of the variable n since regardless of the variable position, you will yet be able to find its value.
